DETAILED DESCRIPTION
[0042] Referring generally to the figures, disclosed herein are
faucets having articulating spouts. That is, each spout includes
one or more segments (e.g., parts, members, elements, etc.) that
can articulate relative to a base and/or other segments of the
spout. The articulating faucets can control the operation (e.g.,
water flow) of the faucet based on articulation of part of the
faucet body, such as a spout of the faucet, relative to another
part of the faucet body, such as a base of the faucet. Traditional
faucets rely on one or more handles or sensors to control such
operation of the faucet.
[0043] By way of example, at least one embodiment disclosed herein
relates to a faucet having a base mountable to a support, a spout
that articulates relative to the base, and a valve operable in an
open position and a closed position to control the flow of water to
an outlet of the spout through which water is dispensed. The spout
can include a plurality of segments operatively coupled together
sequentially, with a first segment rotatably coupled to the base.
The remaining segments are rotatable relative to the first segment
and the base to move the outlet between a first position, in which
the valve is in the closed position, and a second position, in
which the valve is in the open position.
[0044] The plurality of segments can rotate sequentially starting
with the first segment and ending with an end segment of the
plurality of segments. The end segment can include the outlet.
Alternatively, the plurality of segments can rotate randomly or can
rotate substantially simultaneously to move the outlet between the
first and the second positions.
[0045] Each segment can be rotated by an electro-mechanical
actuator, such as a motor and/or a cable operatively coupled to the
motor and to the associated segment so that the motor can rotate
the associated segment through the cable. The actuator can include
a plurality of cables operatively coupled to the motor, with at
least one cable associated with each segment to rotate the
associated segment through the associated cable(s). As another
example, each segment can be rotated by a force created by the flow
of water through the faucet (e.g., to the outlet).
[0046] As another example, each pair of adjacent segments can be
rotatably coupled through a universal joint, a flexible joint, or
any other suitable coupling.
[0047] The plurality of segments can form a substantially
cylindrical shaped spout when the outlet is in the first position
and can form a non-cylindrical shaped spout when the outlet is in
the second position. For example, the segments can form an arcuate
shaped spout when the spout is in the second position such that the
base and the spout together have a substantially inverted J-shape,
and the segments can form a shape that is different than the
arcuate shape spout in the first position.
[0048] Also for example, at least one embodiment disclosed herein
relates to a faucet having a stationary base and a spout. The
stationary base has a first end, which is mountable to a support.
The spout is operatively coupled to a second end of the base, the
spout has an outlet for dispensing water, and the spout is
articulable relative to the base between a first position and a
second position. The base and the spout together can form a
substantially cylindrical shape in the first position and a
substantially inverted J-shape in the second position.
[0049] The spout includes a plurality of segments operatively
coupled together sequentially, where each segment is articulable
relative to the other segments and relative to the base to move the
spout between the first and second positions. A first segment is
rotatably coupled to the base, where each additional segment is
rotatable relative to the first segment and the base to articulate
the spout between the first and second positions. The spout
includes an end segment having the outlet. The end segment can be
detachable from an adjacent segment. A flexible hose can fluidly
connect the outlet (e.g., of the end segment) to the base.
[0050] At least one embodiment disclosed herein relates to a faucet
having a base and a spout. The base extends along a longitudinal
axis and has a first (e.g., bottom) end that is mountable to a
support. The spout includes a first segment movably coupled to a
second (e.g., top) end of the base, a last segment having an outlet
for dispensing water, and a plurality of intervening segments
provided between the first and last segments. Each intervening
segment is movable relative to the first segment to move the last
segment between a first position, in which the intervening segments
align along the longitudinal axis, and a second position, in which
the intervening segments align along an arcuate axis that
intersects the longitudinal axis.
[0051] Each intervening segment includes a hollow inner body and an
outer body. Each inner body has a bore through which a water line
can route, and each inner body is rotatable coupled to the inner
body of at least one adjacent intervening segment. The outer body
is fixedly coupled to the associated inner body such that the outer
body rotates with the associated inner body, and the outer body
defines a portion of an exterior shape of the faucet.
[0052] Each intervening segment includes a bearing that is disposed
in the associated bore between the associated inner body and the
water line. Each bearing has an annular channel that receives an
annular flange of the associated inner body to retain the bearing
relative to the inner body. The inner body includes two or more
parts, such as a first part and a second part, where each part
defines at least a portion of the annular flange. Each intervening
segment can optionally include a magnet that magnetically attracts
another magnet (or ferromagnetic portion) of an adjacent
intervening segment in at least one position.
[0053] One or more cables can be used to control movement (e.g.,
articulation) of the segments. For example, a first cable can be
routed through a first channel of at least one intervening segment
so that the first cable rotates the at least one intervening
segment in a first rotational direction about a pivot axis. Also
for example, a second cable can be routed through a second channel
of the at least one intervening segment so that the second cable
rotates the at least one intervening segment in a second rotational
direction about the pivot axis, where the second rotational
direction is different than (e.g., opposite to) the first
rotational direction.
[0054] Turning to the Figures, FIGS. 1-8 illustrate an exemplary
embodiment of a faucet 100 that is mounted to a support in the form
of a sink deck 90 (e.g., rim, mounting surface, etc.) in FIGS. 1
and 2. A controller 95 can be used to control the functionality
(e.g., turn on/off fluid flow, temperature, etc.) of the faucet
100. As shown in FIGS. 1 and 2, the controller 95 is located
remotely (e.g., separated from) the faucet 100. However, the
controller 95 may be attached to (e.g., part of) the faucet 100.
The controller 95 can control a flow rate and/or a temperature of
water being discharged from the faucet 100. The controller 95 can
be manually operable (e.g., a handle, knob, etc.) or automatically
operable (e.g., including one or more than one sensor). According
to at least one embodiment, the controller 95 controls both the
flow rate and the temperature of water through the faucet, such as
upon rotation. Initial rotation from an off position can turn on
the flow of water through the faucet, where continued rotation can
increase the temperature of water. According to at least one
embodiment, the faucet 100 is turned on and off by one or more
sensors (e.g., detecting presence of a person), and the controller
95 controls temperature of the flow of water.
[0055] Also shown in FIGS. 1-8, the faucet 100 includes a base 101
and a spout 102. The faucet 100 also includes a valve that controls
water flow through the faucet. In an open position, water flows
through the valve to an outlet of the faucet, and in a closed
position, water is prevented from flowing to the outlet of the
faucet by the valve. As shown in FIG. 1, the valve 107 can be
located within the faucet 100, such as within the base 10, or the
valve 107' can be located outside the faucet 100, such as below the
support, depending on the application.
[0056] The base 101 of the faucet 100 is mountable to a support and
is hollow, such as to house other elements/components of the faucet
(e.g., waterway, valve, etc.). As shown in FIGS. 1 and 2, the base
101 has a substantially cylindrical shape extending along a
longitudinal axis LA between a first end 111 (e.g., bottom end),
which is mounted to the sink deck 90 of a sink 80, and a second end
112, which supports the spout 102. The base 101 can be fixed (i.e.,
remain stationary relative to the support) or can be rotatable
relative to the support once mounted to the support.
[0057] As shown best in FIGS. 1, 2, and 4-8, the spout 102 of the
faucet 100 is articulable (e.g., reconfigurable, rearrangeable,
moveable, etc.) between a first (e.g., non-use) position and a
second (e.g., use) position. FIG. 1 shows the faucet 100/spout 102
in an exemplary non-use position with the spout 102 extending
upward from the second end 112 of the base 101 and having a
substantially cylindrical shape that complements the substantially
cylindrical shape of the base 101. Thus, in the non-use position
shown, an outlet 120 of a first end 121 of the spout 102 is
positioned opposite a mounting end/surface of the base 101. In FIG.
1, the outlet 120 in the first end 121 of the spout 102 faces
upwardly away from the sink deck 90 to which the base 101 is
mounted. FIG. 2 shows the faucet 100/spout 102 in a use position
with the spout 102 extending out over the sink 80 (beyond the sink
deck 90) with the outlet 120 positioned to direct water into a
basin of the sink 80. In the use position shown, a second end 122
of the spout 102 is operatively coupled to the second end 112 of
the base 101, and the spout 102 has a curved (e.g., arcuate) shape
that together with the base 101 forms an inverted J-shaped faucet
100. As shown in FIG. 9, a center line of the spout 102 is aligned
along (e.g., coincident with) the longitudinal axis LA of the base
101 in the first position, whereas, as shown in FIG. 10, the spout
102 is aligned along an arcuate axis AA that intersects the
longitudinal axis LA in the second position. Thus, the spout
articulates to change the shape of the faucet, rather than merely
moving the faucet while maintaining the same shape such as with
swivel faucets. Notably, the spout 102 may form other shapes in the
first and second positions. For example, the spout may be
non-cylindrical in the first position and/or the second position,
which may or may not complement the base.
[0058] The spout 102 includes one or more segments 125 that provide
articulation of the spout (relative to the base) between the first
and second positions. As shown in FIGS. 1, 2 and 4-8, the faucet
100 includes nine segments 125a-125i. However, the faucet can
include any number of segments. By way of non-limiting examples,
the faucet 100 shown in FIG. 3 includes eight segments 125a-125h,
and the faucet 100 shown in FIGS. 9 and 10 includes seven segments
(labeled 1-7 in each figure). Notably, the number of segments of
the spout may be tailored, such as to the overall size of the
faucet, the amount (e.g., distance, etc.) of articulation desired,
as well as other suitable design parameters.
[0059] The end segment of the spout 102 includes the outlet 120. As
shown in FIGS. 1 and 2, the end segment 125i having the outlet 120
articulates (e.g., rotate) relative to the adjacent segment 125h,
but the end segment 125i is not detachable from the adjacent
segment 125h. As shown in FIG. 3, the end segment 125h is
detachable from the adjacent segment 125g to reposition the outlet
120 (and end segment) relative to the adjacent segment 125g. The
detachable end segment 125h may be configured to articulate (or not
to articulate) relative to the adjacent segment 125g depending on
the application. The faucet can have a fluid conduit (e.g., a
flexible hose 108 as shown in FIGS. 3 and 23) to fluidly connect
the outlet 120 to a fluid (e.g., water) supply, the base 101, the
valve 107, and/or another element (e.g., component) of the faucet
100. The flexible hose 108, if provided, routes through a cavity or
bore in the hollow base 101 and through the segments as discussed
below.
[0060] FIGS. 16 and 17 illustrate an exemplary embodiment of a
segment 125. As shown, the segment 125 includes a hollow outer body
127 and an inner body 130 disposed within the outer body 127. The
outer body 127 fixedly couples to the inner body 130, such that the
outer body 127 articulates (e.g., rotates) with the inner body 130.
Each outer body 127 defines a portion of an exterior (e.g., an
exterior shape) of the spout 102 and the faucet 100. As shown in
FIGS. 1 and 2, the outer bodies of the segments 125a-125i define
the configuration (e.g., shape, aesthetic finish, etc.) of the
spout 102. The outer body of each segment 125a-125i can complement
the outer bodies of the other segments and/or the base 101. As
shown in FIGS. 16 and 17, the hollow outer body 127 has a
substantially cylindrical shape with a bore 128 that receives the
inner body 130 therein. The outer body 127 can include one or more
locking features 129 that couple the outer body 127 to the inner
body 130. For example, each locking feature 129 of the outer body
127 may include a tab (e.g., detent, arm, extension, etc.) that
engages a corresponding notch (e.g., recess, channel, etc.) on the
inner body 130, or alternatively, each locking feature 129 may
include a notch that receives a corresponding tab of the inner body
130.
[0061] The inner body 130 is disposed in the bore 128 of the
associated outer body 127 when assembled. Each inner body 130
operatively couples to an inner body of an adjacent segment 125
and/or the base 101 (e.g., for the first segment) in a way to
provide articulation of the segment (e.g., the inner body 130)
relative to the adjacent segment(s) and/or base. As shown in FIG.
16, the inner body 130 includes a first part 131 (e.g., first half)
and a second part 132 (e.g., second half) that together retain a
bearing 140 between the first and second parts 131, 132 in a
coupled position. Each of the first and second parts 131, 132
defines at least part of an annular flange for receiving the
bearing 140 to allow articulation (e.g., rotation) between adjacent
segments. As shown in FIG. 16, a first (e.g., upper) annular flange
133 is disposed at one end of the inner body 130 for receiving a
first bearing 140, and a second (e.g., lower) annular flange 134 is
disposed at another (e.g., opposite) end of the inner body 130 for
receiving a second bearing 140 (FIG. 23).
[0062] As shown in FIG. 16, the bearing 140 includes an annular
base 141, a longitudinal bore 142 extending through the base 141 to
house and/or route other elements/components of the faucet 100, and
a flange 143 extending radially outward around at least part (e.g.,
all) of the base 141 at each end of the base 141. The bearing 140
is secured in place by receiving one flange 133, 134 of the inner
body 130 between the two flanges 143 of the bearing 140. Thus, the
flanges 143 and base 141 of the bearing 140 form a channel that
receives one flange 133, 134 of the inner body 130 when the first
and second parts 131, 132 are coupled together.
[0063] Also shown in FIG. 16, each part 131, 132 of each segment
125 includes a magnet 135 that magnetically attracts another magnet
135 (or ferromagnetic element) of another part 131, 132 of an
adjacent intervening segment 125 of the plurality of intervening
segments 125. The magnets can attract in either the first position
or the second position. Each magnet 135 can be embedded in a tab
136 (e.g., projection) extending from the part as shown, or can be
located elsewhere in the segment.
[0064] FIG. 17 illustrates one assembled segment 125 having one
inner body 130 disposed within (e.g., inside of) the bore 128 of
one outer body 127. FIG. 18 illustrates two adjacent segments 125a,
125b operatively coupled together, with the outer body 127b of the
second segment 125b above (and prior to coupling to) the second
inner body 130b. The first inner body 130a is rotatably coupled to
the second inner body 130b through a bearing 140 (like the bearing
140 shown). Another bearing 140 (shown) is disposed at the top of
the second inner body 130b for rotatably coupling to another
segment (not shown).
[0065] FIGS. 19-21 illustrate two adjacent segments 125a, 125b with
the outer bodies 127a, 127b removed to show an exemplary method of
articulating the segments using wires. Each inner body 130a, 130b
includes a first channel 151 for receiving a first wire 161 and a
second channel 152 for receiving a second wire 162. According to an
exemplary embodiment, each wire 161, 162 is braided Kevlar.RTM..
However, other types of wire can be used (e.g., employed). Each
channel 151, 152 is recessed into the body 130 to protect the wire.
As shown, the first wire 161 moves the body 130 (and segment 125)
in a first direction corresponding to the water flow through the
faucet being turned on, and the second wire 162 moves the body 130
in a second direction, opposite to the first direction,
corresponding to the water flow through the faucet being shut-off.
For example, pulling the first wire 161 articulates (e.g., move,
rotate, etc.) the segment 125 to its use position in response to
the water flow being turned on in the faucet, and pulling the
second wire 162 articulates the segment 125 to its non-use position
in response to the water flow being turned off in the faucet. A
portion of each wire (e.g., an end) is coupled to a portion of the
associated body 130 to move the segment 125. As shown in FIG. 21,
an end 163 of the first wire 161 is tied (e.g., knotted) to the
first part 131 of the body 130 to retain the wire 161. Similarly,
the second wire 162 can be tied to the inner body 130. Alternative
ways (e.g., fasteners, adhesive, welding, etc.) may be employed to
retain each wire to the body.
[0066] FIGS. 22 and 23 illustrate three adjacent segments 125
operatively coupled together with the outer bodies 127 removed for
clarity. Two first wires 161 are also shown, with one first wire
161 employed and cooperating with each of the lower two segments
125. During articulation of the faucet, pulling the first wires 161
simultaneously moves the two segments 125 at the same time. The
first wires 161 can be pulled sequentially to move the two segments
125 sequentially, or the first wires 161 can be pulled in other
suitable orders. As shown, portions of the wires 161, 162 route
external to the associated inner body 130 and other portions route
internal to the inner body 130. FIG. 23 shows the two parts of each
inner body 130 separated to see the routing of the wires 161, 162
internal to the bodies 130, as well as the routing of the hose 108
within the bodies 130 (i.e., through the bores thereof).
[0067] FIGS. 24-28 illustrate movement of a top segment 125a
relative to an adjacent bottom segment 125b through the wires 161,
162. FIG. 24 shows the two segments 125a, 125b in a non-use
position (e.g., an initial position with zero degrees of rotation
between the top segment 125a and the bottom segment 125b). FIG. 25
shows the top segment 125a after a rotation of thirty degrees
(30.degree.) relative to the bottom segment 125b by pulling on the
first wire 161 by a first distance in a first direction, which in
turn pulls the second wire 162 in a second opposite direction by
the first distance. FIG. 26 shows the top segment 125a after a
rotation of sixty degrees (60.degree.) relative to the bottom
segment 125b by pulling on the first wire 161 by a second distance
in the first direction, which in turn pulls the second wire 162 in
the second direction by the second distance. FIG. 27 shows the top
segment 125a after a rotation of 90 degrees (90.degree.) relative
to the bottom segment 125b by pulling the first wire 161 by a third
distance in the first direction, which in turn pulls the second
wire 162 in the second direction by the third distance. FIG. 28
shows the top segment 125a after a rotation of 180 degrees
(180.degree.) relative to the bottom segment 125b by pulling the
first wire 161 by a total distance (Dtotal) in the first direction,
which in turn pulls the second wire 162 by the total distance in
the second direction.
[0068] The faucet 100 includes an actuator that controls
articulation of the one or more segments 125 of the spout 102. The
actuator can be a mechanical actuator, an electro-mechanical
actuator, a fluid actuator, or other suitable actuator. A
mechanical actuator can manually articulate the spout 102 by moving
the one or more segments 125 at the same time or at different times
(e.g., sequentially, random). By way of example, the mechanical
actuator can include a knob, a lever, a handle, or other suitable
element that articulates the segments of the faucet 100 upon
actuation (e.g., movement) of the mechanical actuator. Also for
example, the spout 102 can be configured to be manually articulated
by a user whom moves the spout from the first position to the
second position such as by moving the spout itself.
[0069] FIGS. 11-15 illustrate an example of a manual actuator 200
made to conceptually show articulation of the segments 125 of a
fabricated faucet 100. The actuator 200 includes a frame 201, a
plurality of first arms 202 associated with the first wires 161,
and a plurality of second arms 203 associated with the second wires
162. One first arm 202 is provided for each first wire 161, and
each first arm 202 is pivotally coupled to the frame 201 at a pivot
end and is coupled to a portion (e.g., end) of the associated first
wire 161 at (or near) the opposite end. Similarly, one second arm
203 is provided for each second wire 162, and each second arm 203
is pivotally coupled to the frame 201 at a pivot end and is coupled
to a portion of the associated second wire 162 at (or near) the
opposite end. A pulley or pulley system can be employed with each
of the arm 202, 203 to influence the motion of the wire based on
the rotation of the arm 202, 203. Notably, size of the manual
actuator 200 relative to the faucet 100 is not limiting, as size of
the manual actuator 200 shown can be reduced (it was constructed
for ease of actuation).
[0070] The faucet 100 can include an electro-mechanical actuator
that automatically articulates the spout 102. The
electro-mechanical actuator includes one or more motors (e.g.,
stepper motors) configured to pull the wires 161, 162 between the
use and non-use positions. A gearing system (e.g., gear reduction
system) can be employed to control movement of the wires 161, 162
by the one or more motors.
[0071] The plurality of segments 125 of the spout 102 can be
configured to articulate (e.g., rotate) in various ways. For
example, the plurality of segments 125 can be configured to rotate
sequentially in consecutive order, such as starting with the first
segment 125a and ending with an end (e.g., last) segment (e.g.,
segment 125i in FIG. 1, segment 125h in FIG. 3, segment 7 in FIG.
9, etc.) of the plurality of segments 125. With reference to FIGS.
1 and 2, the sequence of articulation would be segment 125a, then
segment 125b, then segment 125c, then segment 125d, then segment
125e, then segment 125f, then segment 125g, then segment 125h, and
then segment 125i. For this method of articulation, the movement of
the segments can overlap (e.g., the second segment 125b can begin
articulating after the first segment 125a begins articulating but
before the first segment 125a is finished articulating) as shown in
FIG. 29, or the segments can move one at a time (e.g., the second
segment 125b begins articulating only after the first segment 125a
is finished articulating, etc.). The segments can be configured to
articulate sequentially starting with a different segment, such as
starting with an end segment and sequencing rearward (e.g.,
descending) or forward (e.g., ascending), or may start sequencing
with any segment and move rearward or forward.
[0072] Also for example, the plurality of segments 125 can
articulate substantially simultaneously to move the faucet 100 and
the outlet 120 thereof between the first and the second positions.
Thus, each segment of the plurality of segments 125 can begin
articulating approximately at the same time.
[0073] Also for example, the plurality of segments 125 can
articulate randomly to move the faucet 100 and the outlet 120
thereof between the first and the second positions. The
articulation can be completely random, where the sequence of
articulation of the segments may be different each successive
articulation. The faucet 100 may include a controller that controls
the random articulation of the segments. The random articulation
can be repeatable randomness, where the sequence is the same from
each articulation to the subsequent articulation, but the order
that the segments articulate is not in consecutive order or
simultaneous order.
[0074] Also for example, each segment of the plurality of segments
125 can be rotated by a force created by a flow of water through
the faucet (e.g., to the outlet). The force can be generated by
water that flows toward the outlet of the faucet (e.g., through the
faucet). In this way, water can route into a first segment, which
then rotates by the force of water from a first position to a
second position; then water flowing from the first segment to a
second segment can rotate the second segment from a first position
to a second position, and so forth sequentially through all of the
segments.
[0075] FIG. 29 shows an exemplary sequence of actuation for a
faucet having seven segments (segments 1-7). As shown, when the
faucet is in a first mode of operation (e.g., an on mode where
water flows to the outlet), segment 1 is the first to begin
articulating, then segment 2, then segment 3 and so forth ending
with segment 7, with each subsequent segment overlapping with the
prior segment (i.e., the next segment in the sequence begins
articulating before the prior segment is fully articulated). FIG.
29 also shows that when the faucet goes from the on mode of
operation to a second mode of operation (e.g., an off mode where
water ceases to flow to the outlet), the segments articulate in the
reverse order with segment 7 articulating first, then segment 6,
then segment 5 and so forth ending with segment 1. Again,
articulation of each segment overlaps with the articulation of the
prior segment. Also shown in FIG. 29, the time from start to finish
going from "on mode" to "off mode" is approximately two to four
seconds (.about.2-4 s), while the time from start to finish going
from "off mode" to "on mode" is approximately one to two seconds
(.about.1-2 s). According to other embodiments, these times can be
reversed or changed, such as to tailor these times.
[0076] FIG. 30 illustrates an additional example of flexible
couplings that can be employed in connecting together adjacent
segments and/or segment(s) to the base, such as the segments 125 of
the faucet 100. The illustrated coupling 210 includes two bushings
211, 212 coupled to a webbing 213 (e.g., a flexible webbing, a
rigid webbing) to allow for rotation of a first shaft 215 engaging
(e.g., received by) the first bushing 211 relative to a second
shaft 216 engaging the second bushing 212.
[0077] FIGS. 34-36 illustrate additional examples of flexible
couplings that can be used with the faucets disclosed herein. FIG.
34 shows a coupling 230 including a first bushing end 231, a second
bushing end 232, and a flexible hollow conduit 233 interconnecting
the first and second bushing ends 231, 232. The bushing ends 231,
232, as shown, are rotatable relative to one another. However,
according to other embodiments, the ends 231, 232 can be rotatably
fixed relative to one another. The conduit 233 can be manipulated
(e.g., bent, moved, compressed, extended, etc.) such as to
reposition the ends 231, 232 relative to one another. FIG. 35 shows
a coupling 250 having a sleeve shape and including a first bushing
end 251, a second bushing end 252, and a non-flexible or less
flexible hollow section 253 connecting the first and second bushing
ends 251, 252 together. The ends 251, 252 can be rotatable or
rotatably fixed relative to one another, and each end 251, 252
includes a bore, which can receive a post, shaft, pipe or similar
member, such as to transmit rotation. One or more set screws 254
can be used to secure a post, shaft, pipe or similar member to an
end 251, 252, such as to transmit rotation. FIG. 36 shows a
coupling 270 that includes a first end 271, a second end 272, and a
flexible hollow expandable corrugated sleeve 273 interconnecting
the first and second ends 271, 272, such that the ends 271, 272 can
flex relative to one another. That is, the sleeve 273 is expandable
and at least somewhat flexible in an expanded position so that the
ends 271, 272 are repositionable relative to one another.
[0078] FIG. 31 illustrates another faucet 400 having a plurality of
segments 421-428 having different configurations (e.g., size,
shape, etc.) relative to one another. The faucet 400 can articulate
into different shapes between or in its various modes of operation,
which do not have to include the more traditional J-shape. The
segments 421-428 allow the shape of the faucet 400 to be
tailored.
[0079] FIGS. 32 and 33 illustrate another faucet 500 having a base
501, which is shown mounting to the sink deck 90, and a spout 502
that operatively couples to the base 501. The spout 502 includes a
plurality of articulating segments. As shown, the spout 502 has
seven segments 521-527 that articulate relative to the base 501 and
to one another. The segments 521-527 are arranged sequentially,
with the first segment 521 coupled to the base 501, the second
segment coupled to the first segment 521, the third segment 523
coupled to the second segment 522 and so forth. The segments
521-527 can have the same shape or different shapes. It is noted
that the number and shape of the segments can produce faucets
having any desired shape upon articulation of the segments.
